    So my 2014 A6 TDI ultra engine oil has recently being saying ďplease reduce engine oilĒ when itís checked on the MMI, I had it into Audi on Friday and they apparently reduced the engine oil to the MAX level and checked using their ďmechanical dipstickĒ. Now my car is back on ďplease reduce engine oilĒ after 3 days. The guy from Audi says itís because I only live 10 miles away from work and the car is not warming up resulting in DPF regeneration fails. Itís then pumping the diesel into the engine oil?? Surely this canít be right... I know there has been a few times itís been in cycle as idle is increased, burning smell and cooling fans blowing but Iíve had to turn it off and leave the car. Is there any truth to this and is there anyway I can initialise a Regen without using VCDS?
    Cheers in advance.

    Yes the flawed dpf system can result in derv in the oil wreaking the oils properties .

    I used to work with a guy who had a fancy BMW and he made a 4 or 5 mile commute daily, his suffered from fuel dilution of the oil and high oil level badly, I think due to frequent active regens during the short journey and engine never getting fully up to temperature. Regens maybe being halted part way through and diesel injected late in the power stroke or on the exhaust stroke to increase dpf temperature not burning off, and washing down cylinder walls into the sump.
    I think your solution is longer hotter and harder driving cycles.

    Thanks for that, suppose it makes sense . But surely that canít be good for the engine? Is there anyway to initiate a dpf regen apart from with vcds?

    Go for a long/hard drive is about the only way to initiate a regen.
    The design is a bit flawed but alot diesel owners do big miles so itís never a problem.
    Problem arises from too much diesel in the oil and that effectively can break things like bearings, turbos etc.

    I wouldn't be driving it at all if the oil has been diluted by the fuel. Diesel doesn't lubricate at all so will be causing damage. Ask Audi to collect the car.

    This is one of the reason I prefer the fixed 10k servicing as you canít tell how much diesel has seeped into the oil
    20k is way too much for any oil

    The car was in before Christmas with a oil leak from the filter housing and they replaced 3.5 litres of oil,so obviously topped it back up after the work was done, but with that stupid mmi gauge instead of a dipstick itís almost impossible to check the level....

    To be honest a diet of ten mile journeys shouldn't break your car so long as you do some longer stints, preferably minimum one per week. My office used to be a mere three miles away and I did eight months of that with no problems.
